1) Hook of the hamate fracture. The hamate bone is on the pinky side of the wrist and can cause pain and ultimately can break in any racquet or stick sport. Baseball players are most at risk. We believe that the pressure from the baseball bat exerts a force on this unusually shaped bone. Over time, pain can develop but initially it might be minor for some patients. But once the bone breaks, more significant pain develops. If not treated over months or years, other problems can develop related to nearby structures including flexor tendons and the ulnar nerve.
There are few reasonable treatment options for a hook of the hamate fracture. While casting can be considered, healing of the bone is unpredictable. Therefore, for most players, this small piece of bone is simply removed. Surgery is generally safe and return to play can be as soon as 6-8 weeks although in some players, it will take longer.
